You're not completely wrong, but that's not quite right either. We already live in a society where it is not alright to eat certain animals. A society where we extend our empathy beyond just humans, and shape our behavior towards animals in other relationships then consumer and food. Lots of people feed birds, keep pets, or have moral objections to eating certain animals, such as horses. These values too have shaped society. Our ability to redefine our bonds to these animals has brought more than just joy: It has aided humanity greatly through the breeding of dogs as companions, horses as beasts of burdens, and cats for whatever (
).
Naturally, despite us redefining our relationship with certain animals, and having the ability to empathize with species beyond our own, this has not led to us ending the practice of eating meat. Just because you are able to empathize with something or someone, doesn't mean you do. And in particular, you do not do so if it significantly impacts your wellbeing or survival. For example, I like mice. They are adorable and interesting. And if they start eating the food I need to survive, I will kill the little bastards without doubt.
My point is, we were never in any position to redefine our relationship with the species we use as food to any real degree, because meat has always been a vital resource. Even if 50 years ago all animals on the planet suddenly had become sapient and fully capable of speech and emotion, most of Humanity would have continued to eat them to survive. Things are
becoming different now though. Living without meat is increasingly becoming something you can survive doing without extreme difficulty. It remains a challenge, and has costs. But it looks like we are heading into a future where you can make the choice to get all your vital sustenance without relying on the flesh of living beings.
So, now is a good time to start asking the questions. To see if we want to redefine our relationships with the remaining species we use as food. The answer for everyone will be different. Mine is "It's not worth it to switch over to a new meat completely yet." Some never will. Some have already. All of those are valid choices. But I just can't respect people that go "
I don't have a choice to make, because things have always been this way". Appeals to Nature are just an excuse to avoid thinking and choosing.
